摘要
随着国家经济的不断发展,交通运输等基础行业发生着日新月异的变化。折叠臂式高空作业车作为专用起重运输汽车的一种,它可以将工作人员和工作装备运送到达指定现场并进行作业的专用汽车。折叠臂式高空作业车主要用于邮电通讯、市政建设、消防救护、建筑装饰、高空摄影以及造船、石油、化工、航空等行业。它具有机动灵活、转移迅速、覆盖面广、便于接近、到达作业地点后能迅速投入工作等优点。而且折叠臂式高空作业汽车结构比较简单,改装比较容易,因而发展比较快。
本设计主要内容是选择合适的二类底盘,在此基础上对折叠臂式高空作业车的主要工作装置进行设计。通过对支腿机构、举升机构和回转机构的设计,进行各个应用元件布置,并采用液压系统对各个元件进行控制以实现举升和回转运动功能。同时,还对折叠臂式高空作业车的附件进行了简单的设计,并对折叠臂式高空作业车的稳定性进行了计算分析,结果表明基本达到国家对改装车的标准要求。

ABSTRACT
With the country's economic development, transportation and so on the basis of an ever-changing industry. Folding-arm high above the ground as a dedicated car lifting of a transport vehicle, which can be the work of staff and equipment arrived at the designated on-site delivery and operation of the Special Purpose Vehicle. Folding-arm high above the ground the main vehicle for posts and munications, municipal construction, fire rescue, building decoration, high-altitude photography, as well as shipbuilding, petroleum, chemical, aviation and other industries. It has a flexible, rapid transfer, coverage for close to reach the sites quickly after getting a work of the advantages. And arm-folding high above the ground vehicle structure is relatively simple, relatively easy modification, and therefore faster development.
The main content of this design is to choose a suitable chassis in the second category, on this basis of arm-folding work high above the main work of the car plant design. The outrigger body, lifting and turning the body design, ponents for various applications. And the use of the hydraulic system to control the ponents in order to achieve lift and rotary motor function. At the same time, also folded-arm high above the ground Annex cars were simple design, and folded-arm high above the ground vehicle for the stability of the calculation and analysis, results showed that the modification of the basic national standards of vehicles.
